Dichlorodiphenyltrichloroethane (DDT) Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agriculture. The United States banned the use of DDT in 1972, but some countries still use the chemical.
DDT finally linked to human health problems. Pregnant women exposed to the insecticide DDT are much more likely to give birth prematurely, or to full-term but low birth weight babies, says a US team. Although DDT is now banned in the developed world, it is still widely used elsewhere to combat malaria, particularly in Africa. âOne of the reasons this finding is important is there are not any generally accepted adverse health effects of exposure to DDT or its metabolite, DDE, in humans,â says researcher Matthew Longnecker of the US National Institute of Environmental Health Sciences in North Carolina.
